Honestly, I've never had much luck with burnishing tools and gum. It always seems to leave a waxy buildup that attracts dust over time. I've gone back to just using a very sharp blade and a steady hand for the initial cut, followed by light sanding with a high grit paper. A clean cut from the start beats trying to fix it later with paste.

Ugh, that's the worst feeling! I had the same thing happen with a cheap one from a craft store. It's like they're made of foil. I switched to Alvin brand shields years ago and they're solid. The metal is thicker and the cut-outs stay sharp. It's worth the extra few bucks to not fight a flimsy tool.

My uncle's deck looked fine until we tried to put furniture on it.

Man, I always thought that was overkill... until we had a comeback. Found a tiny leak in a feed line that would've left someone stranded. Now we catch stuff like weak pumps or stuck regulators every few jobs. It saves so much headache down the road. Changed how I see doing the job right.

Actually, saving all those screenshots is just a waste of space. The toast theory was probably a dumb joke people overreacted to.
